He put the the fence together with small pieces of 1x2 and brad nails. Then sprayed (messily, to create the dirty/blotchy look) it with black and brown spray paint
The web was made with 1/4 inch white rope and zip-ties. Then he attached limbs, animals and bones in the web. They were wrapped with some of the webbing (you know, that stringy stuff you buy to create your own webs), but then we got a load of snow that sort of washed it all away).
A few of the headstones.
The fence of reaching hands.
The warning sign.
He placed a wheelbarrow with skeletons and bones inside along with dirt (and a few red string lights) in the graveyard as well.
His moving coffin. It had a sensor on it so when you passed by, the lid would lift up and down as if someone were trying to get out. He even attached the fake arms sticking out to make it look more realistic. Kinda neat. The kids loved it though.
Ah. The ginormous spider. This guy lowered and raised 2 feet on a string (rope).
My husband made him out of paper mache and PVC tubing and insulator.
And here's a few shots at night for spookier effect.
And for a lasting effect (HA!), here's a little video for you all.
